7.6 CONFIGURATION REGISTER E (ADDRESS 04H)
7.6.1 Max Power Correction Variable
By enabling MPC and setting MPCV = 1, the max power correction becomes variable. By adjusting the
MPCC registers (address 0x27-0x28) it becomes possible to adjust the THD at maximum unclipped power
to a lower value for a particular application.
7.6.2 Max Power Correction
Setting the MPC bit corrects the DDX-2060/2100/2160 power device at high power. This mode will lower
the THD+N of a full DDX-2060 DDX
7.6.3 AM Mode Enable
The STA323W features a DDX
frequency range of AM radio. This mode is intended for use when DDX
active AM tuner. The SNR of the DDX
than the SNR of AM radio.
